﻿Angle of Incidence vs. Angle of Reflection
October 23, 2011 by alison12 · No Comments · Uncategorized...Angle of Incidence vs. Angle of Reflection
Background Information:
Reflection is the change of direction of light. The angle a light ray makes is the same after reflection occurs as it is before reflection occurs. Reflection is the image seen when looking into a mirror, still water, or a polished surface. The reflected image seen will be the same as the object which is being reflected.

Questions
1. What is the relationship between the angle of...incidence and the angle of refraction?
The angle of incidence (formed by the ray of light travelling though air into a slab of rectangular perspex) is not directly proportional to the angle of refraction (angle formed between the ray travelling though perspex and the normal). The graph of the plotted angles of incidence against the angles of refraction is not a straight line and therefore demonstrates...

Refraction of light in water
Refraction is the change in direction of a wave due to a change in its transmission medium. Due to change of... medium, the phase velocity of the wave is changed but its frequency remains constant. This is most commonly observed when a wave passes from one medium to another at any angle other than 90° or 0°. Refraction of light is the most commonly observed phenomenon,
When light travels from air into water, it slows down, causing it to change direction slightly. This...

ABSTRACT
Ordinary...light such as that from a light bulb is a form of wave motion that consists of electrical and magnetic fields that vibrate at right angles to the direction of travel of a light beam. Light waves that vibrate in a single plane are called polarized light waves. Such waves can be produced by passing light through polarizing filters. The experiment conducted was composed...

and a prism, it shows and tells you underneath each of the objects picture a description of what happens when light ray is shone... on it.
The source of light is a light bulb from a ray box. If a beam of light of one colour is shone through a prism, the direction of the beam is changed by the prism. This is because the two faces of the prism through which the light passes are not parallel. If white light is used the prism splits up the light into a series of colours. This shows that white light is actually...
